[SOLVED] audio in does not work (audio out works)

[ScoutDog]

Hi,

I have Gentoo amd64 on Gigabyte M61PME-S2P, which uses nForce 430. I am using ALSA and nVidia drivers. Audio output works, but there is no signal from the mic. alsamixer shows mic as enabled. Could you give me some pointers what to check?

Try a different mic?

This is a serious suggestion, hardware failures are often ignored until the last point.

Both mics which I tried work on another system

Hi ScoutDog,

have you set capture for your Input-device?
Try to start alsamixer push tab to switch into another view.. (playback,capture,all..) and your Arrow-keys for switching and Space for set/unset the Capture, for the "device in your focus".

For me this isn't intuitive (capturing and record sound-input).. on some boards you have set the mixer/capture-device too.. not only this space thing.. its like a mixer option.. like an old tape-drive.. if you want to record from sound-in, from tabe B or from aux. This mechanism isn't on all boards/soundcards, but on some...

Also you have to take care that there isn't a device/mixer set to mute, that you must use. (Like Mixer, Mic or the Capture...).

Regards

Chris

P.s.: To mute unmute use M (when useing alsamixer).
